Comment (by tools400):

 Thank you all for your fast reply. I understand your points and I
 basically agree, that the fix is like papering the actual problem. On the
 other hand that is the same as what rtrim() does now, but without messing
 up the debug log.

 Nevertheless I suggest closing the pull request. Unfortunately I do not
 have the time for trying to recreate the problem with a clean WordPress
 install. And even worse I do not know when that situation will change.

 But of course I will get back to you in case that I figure out something
 new and helpful.

 "Which version of PHP are you using?"

 My server uses PHP 8.1.16 (ionos.de)
